Abstract

Terahertz transverse-magnetic-polarized waves localized on layered superconductor defect in photonic crystals

Highlights

  • During recent years, layered superconductors attract great attention due to their special electrodynamic properties

  • The anisotropy results in the existence of the specific electromagnetic excitations in such layered media, known as the Josephson plasma waves (JPWs), see, e. g. [3, 4] and references therein

  • In works [6, 7] it was theoretically demonstrated that the surface Josephson plasma waves (SJPWs) can propagate along interfaces between layered superconductors and vacuum, to the surface plasmon-polaritons in the case of usual plasmas

Summary

Introduction

During recent years, layered superconductors attract great attention due to their special electrodynamic properties. The unit cell of the photonic crystal is composed of two non-magnetic dielectric layers with thicknesses d1 and d2 , see Fig. 1. The interaction of an electromagnetic wave of frequency ω with the defect of layered superconductor can be described by the effective permittivity tensor that has the following components
